<p class="MsoNormal">Happy to be of assistance – I hope you’ll stay engaged with the list and perhaps join us in helping others as you build your skillset/expertise (best way to learn is through teaching)!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">(1) If I place a new shell directly above an existing shell, how to I tell eQuest that the existing shell's roof is no longer exposed to the outdoors? I'm wondering how to do this in both Wizard mode and Detailed mode. (A work-around I've
come up with is to set the existing shell's roof to an impossibly high R value.)<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in"><span style="color:#009900">In wizards, where you have a dropdown to assign a roof construction, there’s an option to say “No exterior exposure (adiabatic).” This is the most direct way to handle this from the
wizards, and will result in an adiabatic surface being generated (similar to what happens when you have two shells side by side with overlapping exterior perimeters).<o:p></o:p></span></p>
<p class="MsoNormal" style="text-indent:.5in"><span style="color:#009900">In detailed mode, you can improve on that outcome by changing the interior surface generated this way into a heat-transferring surface (Assigning a construction), for which you’ll need
to assign a NEXT-TO space (typically from the floor above). This is however often a lot of work for very little if any meaningful effect. It may be helpful to first consider whether and where you anticipate a significant state of temperature differences
for which intra-zonal heat transfer is something you want to quantify/incorporate.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#009900"> In detailed mode, to swing in a simpler direction, you can simply delete any exterior (roof) surfaces that were generated by accident. This could leave a visible “hole” in your model (aesthetic
hit?), but in terms of function you aren’t losing anything relative to assigning an adiabatic surface, other than the thermal mass of that construction.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#009900"> For cases with partially exposed roofs (where the 2<sup>nd</sup> floor doesn’t totally cover the 1<sup>st</sup> floor shell, leaving some actual roof area), I often end up employing a combination
of these techniques to ensure I have the right amount of exposed roof construction, but no other exterior surfaces “sandwiched” between shells.<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span class="size"><span style="color:#4B4B4B;background:white">(2) I have two shells in eQuest, separated by an unknown distance. I'd like to measure the distance between the shells so I can position them as needed. Is there a way to measure
this? I would then go into the shell and adjust its position on Screen 1 in the Wizard ("Specify Exact Site Coordinates"). (Or I could adjust in Detailed mode, although I haven't adjusted shell position in Detailed mode up to this point.)<o:p></o:p></span></span></p>
<p class="MsoNormal"><span class="size"><span style="color:#009900;background:white"> My first response, only appropriate to me and others who typically develop their floor plans in CAD first… is to simply scale off the differences within your
CAD platform of choice. <o:p></o:p></span></span></p>
<p class="MsoNormal" style="text-indent:.5in"><span class="size"><span style="color:#009900;background:white">Assuming you
<u>don’t</u> have that effort in place, this is achievable in Wizards / Detailed, but I think easiest in Wizards, if you have the option:

<li class="MsoListParagraph" style="color:#009900;margin-left:.25in;mso-list:l1 level1 lfo2">
<span class="size">I would personally advise, for sanity reasons, starting by ensuring all shells are positioned using exact site coordinates, with X & Y = 0.
<b>This will ensure all shell geometries share a common X/Y coordinate-system. </b>I kind of wish this was the default behavior for the wizards, as I consider it a best practice that will help beginners avoid/simplify a series of potential pitfalls in shell
positioning. Allow Z coordinate to vary for different shell elevations.<o:p></o:p></span></li></ol>
